I have to say, since I never went into the vet, I have no idea if her tumors were cancer or if they were fatty tumors. All I can say was they were huge and hard, but responded phenomenally well to the colloidal silver. But I do know from all my research on colloidal silver that it is supposed to work against cancer and may change cancerous cells to stem cells, so that the cells could restore themselves back to what the were meant to be.
Since I've been taking colloidal silver myself, I have had moles getting smaller.
